Definitions

  • the tight connection of a flexible tube and a rigid pipe is obtained, after fitting the flexible tube onto the rigid pipe, by means of a clamp.
  • the latter generally consists of a metal strip wound on itself, the two ends of the strip comprising complementary fastening and / or tightening members; it has, on the other hand, before its installation on the flexible tube, a diameter appreciably greater than that of the tube so as to be able to slide easily along the latter to the intended location where it must be tightened .
  • the collar is mounted on the flexible tube and brought into the axial position which it must occupy during tightening, prior to the fitting of the tube on the rigid pipe. This last operation must then be accompanied by a suitable angular orientation, so that the collar can be subsequently tightened.
  • the invention therefore firstly relates to a method to facilitate, before tightening, the mounting of a collar intended to be tightened on a flexible tube fitted on a rigid pipe.
  • mounting or “fitting” of the collar, is meant here both the axial positioning of the collar relative to the rigid pipe and the flexible tube as its angular positioning, taking into account the requirements, recalled above, at the time of Tightening.
  • the collar is fixed, by its outer periphery, in a receptacle capable of being linked, axially and angularly, to the rigid pipe, prior to the mounting of said collar on the flexible tube.
  • the fitting of the flexible tube onto the rigid pipe does not require any particular angular orientation precautions, whether this fitting is carried out before or after the connection of the receptacle to the rigid pipe.
  • the receptacle will advantageously constitute a single piece with the rigid pipe so that the collar can be fixed at any appropriate time in the receptacle.
  • the invention also relates to a device, called a pre-assembly ring, allowing the implementation of the process defined above and essentially comprising a receptacle for a clamp.
  • such a receptacle essentially consists of a generally cylindrical sleeve made of flexible material, for example plastic, one end of said sleeve being provided with a groove, generally annular, on its inner wall, the depth is substantially equal and, preferably, slightly greater than the thickness of the metal strip constituting the collar.
  • the wall of the sleeve has, on the other hand, opposite the groove, an opening intended to allow access to the complementary fastening and / or clamping members of the collar.
  • a clamp will, for example, be of the type described in European patents AE 3199 or AE 113624 or even in French patent application 8701426. More generally, the clamp is essentially constituted by a 2a metal strip wound on itself, its two ends being provided with complementary members 3a, 3 b for hooking and / or clamping.
  • the receptacle for the pre-assembly ring consists of a sleeve 4, generally cylindrical, made of flexible material, for example plastic. At one of its ends (on the right in FIGS. 1, 2 to 3), the sleeve 4 has in its inner wall a groove 5, generally annular. The depth of this groove, intended to receive the collar 2, is close to the thickness of the metal strip constituting the collar. Preferably, however, it will be slightly greater than this thickness so that the collar is well embedded therein and is not likely to leave its receptacle during handling of the ring before it is mounted on a rigid pipe.
  • the wall of the sleeve 4 has, on the side of the groove 5, a plurality of longitudinal slots 6 open towards the outside.
  • the slots 6 Preferably, regularly distributed over the periphery of the sleeve, the slots 6 define in the wall of the sleeve tabs 4a, radially deformable.
  • an opening 7 is cut in the wall of the sleeve 4, facing the groove 5 which therefore no longer exists locally.
  • This opening constitutes a housing for supplementary 3a bodies, 3b fastening and / or tightening of the clamp 2, which will be accessible from the outside of the sleeve, upon tightening of the collar will be described later.
  • the collar 2 is introduced into the receptacle by any appropriate means and the tabs 4 ′ of the sleeve are raised until the collar has taken place in the groove 5 where it is held by its outer periphery.
  • the edges 7a, 7b of the opening 7 constitute stops for at least one of the members 3b for hooking and / or tightening the collar 2.
  • the angular position of the latter in its receptacle can therefore be defined relatively precisely by the support of one of said members on one of the edges of the opening 7.
  • Other equivalent means could however be provided in correspondence on the ring 1 and the collar 2 to ensure the angular indexing of one relative to the other.
  • the sleeve 4 On the side opposite to the groove 5, the sleeve 4 is extended and its second end comprises means, which will now be described, making it possible to subject it to a rigid pipe.
  • a rigid pipe 8 on the free end of which is fitted a flexible tube 9.
  • the rigid pipe will be, for example, a nozzle mounted on a radiator for a motor vehicle, while the flexible tube 9 is the hose connecting the engine to the radiator, ensuring the circulation of the coolant in the engine.
  • the rigid pipe 8 has a flange or shoulder 8a, which can be attached or on the contrary machined at the same time as the end piece.
  • the 8a shoulder itself has a slight longitudinal protuberance 8 b , the usefulness of which will appear later.
  • the sleeve 4 has, for its part, an annular housing 10, at its end opposite to the groove 5.
  • the housing 10 is delimited by an internal transverse wall 10a whose internal diameter is less than that of the sleeve 4.
  • the external transverse wall 10b of the housing is essentially constituted by a flange directed towards the axis of the sleeve and having an external face 10c frustoconical.
  • Longitudinal slots 11, open towards the outside, and preferably angularly evenly distributed, are formed in the wall of the sleeve and define, in the area of the housing 10, a plurality of deformable tabs 12.
  • the collar 2 will have been placed in the groove 5 as described above.
  • the ring 1 is then engaged, by its end opposite to that receiving the collar, on the free end of the end piece 8, on the left in FIG. 2.
  • the tabs 12 are raised until the external wall is clipped behind the shoulder, the internal wall 10a then coming to bear on the latter.
  • the pre-assembly ring is positioned axially with respect to the rigid pipe 8, the shoulder 8 of which is disposed inside the housing 10.
  • the pre-assembly ring 1 can however still rotate on the rigid pipe until the protuberance 8b of the shoulder is capped by one of the slots 12.
  • any other means can be provided on the pre-assembly ring of angular indexing to cooperate with the protuberance 8 b .
  • the pre-assembly ring 1 and the rigid pipe 8 will include complementary means allowing angular indexing of one relative to the other.
  • the collar 2 is angularly indexed relative to the pre-assembly ring 1, so that after the latter has been placed on the pipe 8 the collar 2 is positioned, as well axially than angularly, relative to it.
  • the flexible tube 9 can then be fitted onto the rigid end piece 8 without taking any angular indexing precautions.
  • the fitting can be carried out by automatic machines of the robot type.
  • the tube will reach its final position on the end piece when its free end comes to bear on the internal wall 10a of the housing 10 of the pre-assembly ring or in the immediate vicinity of this wall.
  • the collar 2 can then be clamped by the conventional means disclosed in the patents cited above, or by any other means appropriate to the complementary bodies 3a, 3b hooking and / or clamping.
  • the complementary bodies 3a, 3b hooking and / or clamping.
  • the collar 2 will always be well positioned axially with respect to the end piece 8, in particular if the latter has, as shown in FIG. 2, ribs 8 c and 8 d intended both to improve the tightness of the connection and to prevent any sliding of the tube 9 on the pipe 8, after tightening of the collar.
  • the latter could not indeed be moved axially during the fitting of the tube on the pipe since it is retained by its outer periphery in the pre-assembly ring 1 and that its diameter before tightening can be significantly greater than the diameter outside of tube 9.
  • the pre-assembly ring which has been described above.
  • the same elements as those already described carry the same references, the pre-assembly ring being itself designated by the reference 1 ⁇ .
  • the ring 1 ⁇ constitutes a single piece with the rigid pipe 8 (or end piece). This arrangement will advantageously be used when the end piece is molded in plastic, but could also prove to be advantageous in the event that it is machined.
  • the angular indexing of the ring 1 ⁇ is obtained without any particular means since it is no longer necessary to provide a housing for a shoulder of the pipe.
  • the ring 1 la has a groove 5, quite similar to that which has been described above, to receive the collar 2 and maintain it by its outer periphery.
  • the collar 2 After manufacture of the end piece 8 and of the ring 1 collier, the collar 2 is placed there in the manner described above, in general before the fitting of the tube 9 on the end piece.
  • the collar 2 can itself be angularly indexed relative to the ring 1 ⁇ , if this proves useful.
  • the clamping operations of the collar are similar to those which have already been described and the advantages which result from the invention are preserved by this embodiment of the pre-assembly ring.
